To aZZ whomz'tmay concer/ft.'

Be it known that I, CHARLES W. TREM- EER, a citizen of the United States,l residing at New Haven, inthe county of New Haven and State of Connecticut, haveinvented a new 4and useful Improvement in Sheet-Feeding Mechanisms; andl I do herebydeclare the following, when taken in connection with the 'accompanying drawings and the characters of reference marked thereon, to beta full, clear, and exact description of the same, and which said drawings constitute part of this application, and represent, in-n f Fig. 1 abroken plan view of a sheet-feeding mechanism constructed in accordance with my invention. 'v n Fig. 2 a sectional view on the line 2 2 of Fig. 1, the parts vbeing shown as in position ready to receive a sheet.

a sectional view on the line 4-4 of This invention relatesto improvement in sheet-feeding mechanism', and, while par-.

ticularly adapted for use on printing-presses, is adapted for folding machines vand for feeding sheet-metal, or other material, which isliable to buckle, or rebound as it is`delivered. In printing-presses in particular, intransferring the sheet from the tape-to the. ,cyl'inders, it is desirable to straighten-'and tov retard the movement of the sheet and gradually bring it to a stop, as it is in position to be gripped bythe cylinder fingers. The object of this invention is to provide mechanism which will so straighten and retard the movement of the sheet, and the invention consists in the construction as hereinafter described and particularly recited in the claims.

'The construction of the device may be best understood in connection'with a descriptionof its operation.

The forward edge of a sheet of paper, or' other material, 10, delivered -by th'eusual' tapes A1'1, or other means, enters between a finger 12, mounted in the lower end of a guide-plate 13, andthe lower rvface'of a deector or top guide .14, lthis deflector being mounted upon an extension 15 of a block 16 adapted to travel on a bar 17 being held in place by a plate 18. The bar is supported by a frame 53, and pivoted to the block roller 48a travellingin vthe slot 49.

on anistudflQlis astop-carrier 20, this stop- -carrier'being provided-with a forwardly-extending screw 21 having a head22`threaded l toreceivean adjusting screw 23 havingla knurled operating head 24, the screw passing through the upper-end 'of the plate13, which is swivelly connected with the screw bya-washer 25,-whereby, when the screw 23 is turned up or down, the guide-plate will be movedv with it, and it may be heldin its adjusted l'position by a lock-nut 26. The screw 21 may be adjusted in or out by a capstan-nut 27 and when adjusted it may be locked by a set-screw 28 and1 lock-nut'29. On the stud 19 is a helical spring 30, one end-ofjwhich enters the stop-carrier 20 and the other enters a tension-adjusting collar 31 having notches l32 to engage with a pinv 33 on the stud `19. The normal function of-the `spring 30 is to eXert a constant effort to hold the guide-plate 13 in its retired position, as

20 is a pin 35 which is engaged by a latch 36 pivoted on a stud 37 carried bythe eX- tension 15. i This stud is encircled by a spring 38 bearing against anadjusting collar 39 formed with notches 40`-to engage with a pin 41'in the stud 37, the other end of the spring entering the-latch v36 and tending'todepress it,this latch being 'provided with alatching-face 42,- to be engaged by the pin35. fln the outer end of the latch 36 is a transverse pinv43 `adapted to be engaged by a tripping-block44mounted on the end of the bar-17.y Mounted-on the top of thestop-carrier 2O is a. re-setting-arm 45 adapted to engage with a tie-bar 46 to swing the stop-arm 13 from the position shown in Fig. 3 to theposition shown in Fig. 2. -Pivotally connected' with the top of a block 16 is av long' link 47, its other end being mounted on a bolt 48 yextending through a slot 49 in a driving-arm 50, and a short link 5'1 is also' `connected with the bolt 48 and with a pivot 52 mounted .in a frame 53.' The bolt 48 carries'at its outer: enrlh a e frame l53 'is mounted on a driving-shaft 54 and onthe'tie-bar 46, both of which are supported in brackets 55`on the usual feedboard 56, which has the usual projecting feed-plate 57 extending vtoward the presscylinder 58. A duplicate mechanism is ar'- ranged at the other side of the machine.

c so. enters, thef arm-50. startsk Mounted on :thenouter end: of the i drivingshafti is an'k operatingdever v59 connected by a link 6() with a driving-crank or eccentric- 61 which maybe located 4at any con-v venient point on the machine. l

Assuming that a'sheet f material is'b'eing delivered by the tape 11,.itsledge will extend between the linger 12 and the deiiecting-plate 14C and be thereby. straightened, the mechanism being soy timed that as it to vswing forward, moving ythe links. if-Jand 751. and Amoving. the blockl fonward, Sand Vthis is: at va f speed `slightly less --than the speed-"f A the permitting-.the Vspring 30v -to rook 1 the stopcarrier 201and .throwthefguideplate' '13l upwardiiinto its retiredfposition, as-sh/o'v'vn in Figj ofthe drawings. Thewsheet is then free'to `be-.drawn ontothe cylinder inthe usual way.v In ythe Vcontinued :movementl of the device, Vthe-block is drawnrearward f into setting-arm. 45,engaging -with the tie-rod'46, turns the sstop-earr-ier 20,with'its pin, into position to belengaged 'by vthe latch *36, thus re-setting-.the .mechanism 'ready to engage the neXt sheet.
